When Pablo Medina started using the CeQur Simplicity patch, he loved the freedom it gave him. No pens in his pocket, no need to pull out supplies at a restaurant, just a simple click when he needed insulin. But after using a smart insulin pen, one feature was missing — there was no way to see how much insulin was left in the patch or how much he had dosed throughout the day. With a 4-day patch and a busy life in New York City, going blind felt like a real risk.

So Pablo built the tool he needed. With his medical training from Cuba and his growing experience in software engineering, he designed a simple Insulin Patch Tracker app that tracks doses, shows remaining insulin, logs insulin on board, and sends alerts when the patch is running low. No accounts, no extra steps, just clean information when it matters. He tested it for months, fixed bugs, added insights, and shaped it into something that works in real life, not just on paper.

This is another reminder of how often people with diabetes create the tools that move this space forward. Pablo wanted better tracking for his patch, so he made it. Now anyone can download it from the App Store for free.

In this week’s episode we break all of this down with Pablo Medina, who shares how his diagnosis pushed him into experimenting with different devices, what inspired him to build the app, and how he is thinking about future tools for people with diabetes. You can listen to the full conversation above or watch the video below to hear the full discussion in detail.
